passes through a circuit network. Connect the oscilloscope with the circuit and
monitor the input and output signals of the circuit.
Note:
In this mode, the “To Adjust the Horizontal Position”, “To Turn Delayed
Sweep On/Off”, “To Specify the Acquisition Mode”, “Trigger”, “To Make
Math Operation”, “To Make One-key Measurement”, “To Specify the
Measurement Range”, “Protocol Decoding”, “Reference Waveform”,
“Pass/Fail Test”, “Waveform Recording” and “Vectors” are not available.
The “X-Y” cursor mode (refer to “X-Y Mode”) is only available in this time base
mode.
If delayed sweep is currently turned on, when the “X-Y” mode is turned on, the
delayed sweep will be turned off automatically. When the “Y-T” mode is turned
on again, the delayed sweep will be turned on automatically.
Phase Deviation Measurement Principle
The phase deviation between two signals with the same frequency can be easily
measured via the Lissajous method. The figure below shows the measurement
principle of the phase deviation (assume that the amplitudes of the two signals are
the same).
